Illegal fireworks blamed for road collapse

A TRUCK that exploded and caused an elevated stretch of highway to collapse in central China, killing 10 people, was loaded with holiday fireworks that were illegally produced and transported, authorities say.

Local authorities have shut down the company that made the fireworks, Hongsheng Fireworks Manufacturing Co Ltd, and detained four company officials following Friday's blast, state media reported on Saturday.

It remained unclear what set off the fireworks as they were shipped eastward on a major highway through Henan province. State-run China Central Television said witnesses believed a collision caused by heavy smog might have triggered the blast, which occurred about 90 kilometres west of the ancient city of Luoyang.

The Ministry of Public Security said Hongsheng, based in the neighbouring province of Shaanxi, had illegally produced the explosives, packaged them in disguise and contracted with a trucking company unlicensed to handle hazardous commodities.

It said the factory had failed to check the credentials of the trucking company's personnel.

The state-run China News said the explosives had been declared as general commodities.

Preliminary investigations blamed the explosion for the collapse of the 80-metre stretch of the elevated highway in Mianchi county, sending trucks and sedan cars plummeting 24 metres to the ground, according to a statement by the provincial government of Henan.

Most of those who were killed died from the fall, CCTV said. Eleven people were injured.

Photos by state media and television footage showed hunks of concrete, overturned trucks and crumpled cars in the debris. In one photo, a truck's back wheels were perched at the edge of a shorn-off section of the highway.

"It was horrible. It was horrible," survivor Hou Chunlin murmured from his hospital bed in an interview by CCTV.
